Excitable … that is what you call one who reacts with great swings
upward in the face of events.  Picture a
pot of boiling water that simmers.  Turn
up the heat and the bubbles boil with great fervor.  Do you boil and pop when the heat is turned
up?  It is not necessary.  In the physical world, this is the normal
reaction, but you are not of this world. 
Remove yourself from the stove when things get too hot for comfort.  Allow things to cool down as you observe and
decide if you want to be part of the stew. 
Like a fine seasoning, you add a unique flavor to the mix, but you need
not blend in completely.
